bridge: netlink: add support for multicast_startup_query_count
Add IFLA_BR_MCAST_STARTUP_QUERY_CNT to allow setting/getting br->multicast_startup_query_count via netlink. Also align the ifla comments. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
